Except he didn’t. His New York Comic-Con entry badge tweeted it for him. The same thing happened to hundreds of other attendees, including members of the press and celebrities, and some of them are hopping mad about it.

Chelsea Stark at Mashable explained that this year’s badges are equipped with radio-frequency identification chips linked to the holder’s identity. In practice, the chips are for curbing counterfeit badges.

That’s not the only use, though. Attendees were given the opportunity to connect their Facebook and Twitter accounts to their badges, too. Doing so apparently gave convention organizers tacit permission to tweet on the badge holders’ behalf, though many of those badge holders say that wasn’t part of the deal.

That said, there’s no clear warning on the page about badges on the NYCC website, nor is there anything on the activation page. That doesn’t mean there wasn’t a warning in the fine print somewhere, though.

In a further statement to Polygon, a convention spokesman said, "This was an opt-in function after signing in, but we were probably too enthusiastic in our messaging and eagerness to spread the good word about NYCC. We have since shut down this service completely and apologize for any perceived overstep."
